| Package | Local Description (use.local.desc) | Metadata Description (metadata.xml) |
|---|---|---|
| cross-x86_64-unknown-linux-musl/binutils | - | Build binutils with Profile Guided Optimization (PGO) and LTO |
| cross-x86_64-unknown-linux-musl/gcc | - | Build GCC using Profile Guided Optimization (PGO). GCC will build itself and then analyze the just-built binary and then rebuild itself using the data obtained from analysis of codepaths taken. It does not affect whether GCC itself supports PGO when building other software. This substantially increases the build time needed for building GCC itself. |
